Its summertime and as things heat up, it's always important to keep in mind how to properly store any flammables and keep risk of fires to a minimum. Here are some tips for storing your propane tanks

✅ 1. Always Store Propane Tanks Outdoors

Why? Propane is heavier than air and can accumulate in low-lying, enclosed spaces, creating fire or explosion risks even from a tiny ignition source 

Never store tanks in your home, basement, crawlspace, garage, or underground area 

• The safest place is outdoors, in the open air and away from occupied structures. Detached sheds and well-ventilated garages are acceptable only if they’re fully open and detached .

• Even if your tanks are empty there is a risk and it is important to follow these rules

🧱 2. Keep Tanks Upright on Solid Ground

• Store propane tanks vertically (upright) on a stable, non-combustible surface like a concrete pad or slab 

• Never lay a tank on its side or upside-down—this can render the pressure-relief valve inoperative

• A Reddit prepper reinforces:

• “Standard propane tanks are made to be transported in an upright position.” reddit.com+1reddit.com+1theoutdoorinsider.com+11reddit.com+11ferrellgas.com+11

🌞 3. Keep Away from Heat, Sun & Fire

• Propane tanks must be protected from extreme temperatures. Shade is crucial—excessive heat raises internal pressure, triggering relief valves 

• Never store where temperatures might exceed 120°F (49°C) or drop below –40°F 

• Do not store near any ignition sources: grills, fire pits, heaters, appliances, electrical equipment, or naked flames .

• A Phoenix-based Redditor warns:

  “Keep your tanks in the shade but do not store them in a hot shed with no ventilation. Modern tanks… release gas at temperatures between 110 and 130.” reddit.com

📏 4. Maintain Safe Distances & Keep Secured

• Store tanks at least 10–20 feet away from buildings, property lines, flammable materials, and sources of ignition 

• Industrial and commercial installations often require even greater spacing .

• Use barriers or cages to prevent vehicles, lawn gear, or objects from striking tanks; secure tanks against wind or tampering 

• Reddit advice:

• “I store all the other tanks outside in a 3 sides open covered car port… with a security cable through them to deter theft.” reddit.com

🔍 5. Inspect Tanks Regularly

• Monthly checks should include: rust, dents, corrosion (especially at collar/top), valve integrity, and signs of leaks 

• Check stamped certification dates if applicable.   

• Replace any tank with severe corrosion or structural damage .

🚫 6. Ensure Valves Are Closed & Fitted Properly

• Always shut the tank valve securely when not in use, even if you believe it to be empty 

• For older tanks with internal-thread (POL) valves, fitting a valve plug adds safety when disconnected 

• Never over-tighten or modify valves—don’t use tools that can deform or damage them .

• A Reddit prepper emphasizes for smaller bottles:

  “Avoid leaving the bottles connected to a stove, grill… It's far easier for valves to be left open….” reddit.com

🛡️ 7. Prevent and Detect Leaks

• Use a soapy water test around valves and connections—bubbles indicate leaks 

• Never test leaks with open flames or sparks 

• Typical leak sign: the smell of rotten eggs or skunk 

⚠️ 8. Transport Safely

• Always transport tanks upright and securely strapped so they don’t shift or fall over 

• Keep tanks in well-ventilated parts of vehicles; never leave them unattended in hot cars .

• Close valves fully; even “empty-looking” tanks can contain residual gas

❄️ 9. Seasonal Storage Tips

• Summer: Protect from sun; shade reduces pressure buildup .

• Winter: Elevate tanks off snow/ice; ensure free airflow around them .

• Covering tanks can guard against moisture and rust, but never seal covers over relief valves .

---

📦 10. Label, Rotate, and Dispose Properly

• Clearly label your tanks and use first-in, first-out rotation to avoid keeping old, uncertified tanks .

• Tanks past their certification date or showing defects should be requalified or replaced 

• Empty or damaged tanks must be taken to hazardous waste centers or recycling programs—and not just discarded .

Why These Rules Matter

1. Pressure control: Propane expands with heat; relief valves require upright posture.

2. Flammability: Even small stray sparks can ignite propane in poor ventilation.

3. Structural integrity: Corrosion or dents can weaken tanks; certification ensures safety.

4. Leak prevention: Closed valves, caps, and detectors help avoid unseen leaks.

✅ Final Best Practices

1. Always store tanks outside, upright, on a solid, level surface, shaded from heat.

2. Maintain distance (≥10‑20 ft) from any structure or ignition source.

3. Regularly inspect for rust, corrosion, and integrity; recertify or replace as needed.

4. Secure tanks from tipping or vandalism with cages, barriers, or anchors.

5. Never store in basements, garages, crawlspaces, or indoors—even small 1‑lb cylinders 

6. Check leaks safely with soapy water; don’t use flames.

7. Cover tank valves when stored but never block relief mechanisms.

8. Rotate stock, dispose of expired/damaged tanks properly via recycling centers.

9. Transport safely—valves closed, tank upright, secure and ventilated.

10. Keep fire extinguishers near storage area for emergencies
